[0035] In this embodiment, the fixture base 1 can be a plate-like structure and serve as the structural carrier of the entire fixture. The fixed part 2 and the driving member 4 can be relatively arranged at the two ends of the fixture base 1. The sliding part 3 slides on the fixture base 1 and is located between the fixed part 2 and the driving member 4, that is, the driving member 4 can drive the sliding part 3 to move closer to or away from the fixed part 2. In this way, the second clamping part 6 arranged on the sliding part 3 can move closer to or away from the first clamping part 5 arranged on the fixed part 2, thereby realizing the clamping work. The specific clamping work process is: the workpiece 9 to be processed is placed between the first clamping part 5 and the second clamping part 6. When the sliding part 3 is driven by the driving member 4 to slide in the horizontal direction toward the fixed part 2, the second clamping part 6 can push the workpiece 9 toward the first clamping part 5 and clamp it.

[0036] In this embodiment, during the clamping of workpieces 9 of different sizes, the heights of the first clamping portion 5 and the second clamping portion 6 can be adjusted to adapt to the height required for clamping the workpiece 9. The adjustment heights of the first clamping portion 5 and the second clamping portion 6 can be the same or different, depending on the adaptability of the workpiece 9. In this way, the versatility of clamping workpieces 9 of different sizes is achieved, and the efficiency of clamping workpieces 9 of different sizes is effectively improved.

[0037] In one embodiment, the first clamping portion 5 and the second clamping portion 6 are both provided with a bakelite structure at the upper opposite clamping positions, and the shapes of the first clamping portion 5 and the second clamping portion 6 can be designed according to the shape of the workpiece 9; for example Figure 1 In the U-shaped aluminum extruded profile workpiece 9 shown, the first clamping portion 5 and the second clamping portion 6 may be in a strip shape, and the first clamping portion 5 and the second clamping portion 6 are clamped on both sides of the U-shaped aluminum extruded profile.

[0038] In one embodiment, the driving member 4 is one of a cylinder 41 and a screw motor; this embodiment preferably uses the cylinder 41, and the cylinder 41 is fixedly mounted on the fixture base 1 through a mounting plate structure 43. A retractable push rod device 42 is provided at the output end of the cylinder 41, and the push rod device 42 is connected to the end of the sliding part 3 away from the fixed part 2; in this way, the cylinder 41 can drive the sliding part 3 to slide through the push rod device 42.

[0041] In this embodiment, in order to protect the linear guide assembly 7, a protective shell 31 is provided at the bottom of the sliding part 3. The protective shell 31 is a hollow rectangular frame that penetrates the top and bottom. The bottom of the sliding part 3 is connected to the top edge of the protective shell 31 and seals the top of the protective shell 31. A small gap is left between the bottom of the protective shell 31 and the fixture base 1. In this way, the protective shell 31 can cover the entire linear guide assembly 7 for protection. It should be understood that the protective shell 31 will slide synchronously with the sliding part 3. In order to avoid structural interference between the protective shell 31 and the linear track 71 during the sliding process, the protective shell 31 is extended in the guide direction of the linear track 71 to ensure that sufficient avoidance space is reserved inside the protective shell 31.

[0042] In one embodiment, the clamping fixture further includes two placement portions 8; the two placement portions 8 are installed on the fixture base 1 and are symmetrically distributed on both sides of the sliding direction of the sliding portion 3; the workpiece 9 is placed on the two placement portions 8 and is located between the first clamping portion 5 and the second clamping portion 6.

[0043] In this embodiment, the workpiece 9 needs to be kept stably placed during the clamping process, so two placement parts 8 are set on the fixture base 1. The placement part 8 is a side plate structure. The two ends of the workpiece 9 are placed on the two placement parts 8. The second clamping part 6 can push the workpiece 9 to slide stably on the two placement parts 8 toward the first clamping part 5.

Based on this, by adjusting the height position of the first adjustment block 51 in the slide groove 21 of the fixing part 2, the height position of the first clamping plate 52 can be adjusted.

[0048] In one embodiment, a plurality of mounting steps of different heights are provided on the sliding portion 3 in a direction toward the fixing portion 2 ; and the second clamping portion 6 is mounted on any mounting step.

[0049] In this embodiment, the sliding part 3 includes a bottom plate 32 and a step plate 33. The sliding part 3 is slidably assembled on the linear guide assembly 7 through the bottom plate 32. The second clamping part 6 is installed on any mounting step on the step plate 33 of the sliding part 3. The second clamping part 6 includes a second adjustment block 61 and a third adjustment block 62; the second adjustment block 61 is installed on any mounting step, and a through slot 611 is provided on the second adjustment block 61 along the height direction; the third adjustment block 62 is connected to the through slot 611 of the second adjustment block 61 and can be moved and adjusted in the height direction; the second clamping plate 63 is installed on the end of the third adjustment block 62 away from the sliding part 3, and the clamping surface of the first clamping plate 52 faces the first clamping part 5. Based on this, the height position of the second clamping plate 63 can be adjusted by adjusting the mounting step of the second adjustment block 61 on the step plate 33 and adjusting the height position of the third adjustment block 62 connected to the through slot 611 of the second adjustment block 61. It should be understood that the number of installation steps on the step plate 33 and the height of each installation step can be set according to actual needs, and this embodiment does not specifically limit this.
